Cannabis abuse with psychotic disorder, unspecified

This code signifies a pattern of problematic cannabis use leading to clinically significant impairment or distress, co-occurring with a psychotic disorder. The psychotic symptoms are directly attributable to the effects of cannabis abuse, and the specific type of psychotic disorder is not documented. This diagnosis indicates a dual diagnosis where the substance use is directly linked to the psychiatric manifestation.

Use this code when documentation clearly indicates a patient meets criteria for cannabis abuse and concurrently presents with psychotic symptoms (e.g., hallucinations, delusions, disorganized speech) that are judged by the clinician to be induced by or exacerbated by cannabis use. This code is appropriate when the specific type of cannabis-induced psychotic disorder (e.g., with delusions, with hallucinations) is not specified in the medical record. Supporting documentation would include a psychiatric evaluation, substance use assessment, and a clear statement linking the psychosis to cannabis abuse.

• Ensure documentation explicitly links the psychotic disorder to cannabis abuse; otherwise, consider coding the cannabis abuse and psychotic disorder separately.
• Avoid using this code if the psychotic disorder predates cannabis use and is merely exacerbated, or if the psychosis is clearly due to another underlying mental health condition.
• Always review for more specific codes within the F12.15- category if the type of psychotic disorder (e.g., with delusions, with hallucinations) is documented.
